I like the Heart Warmer better than hot love, and I do have both. The reason is that the Heart Warmer is a bit bigger and stays warm longer. It also has a smoother surface than hot love so it glides over skin better. With Hot Love you do get tow of them, but I still like the Heart Warmer better. I often just use mine during the winter when I'm stuck out shoveling, or when the heat in my car stops working (it does this from time to time).
